MORAb-004 is a monoclonal antibody directed against endosialin, a cell surface glycoprotein, which is expressed on cells involved in tumor vasculature. Studies have found endosialin to play a key role in tumor growth and neovessel formation in numerous cancer types including (but not limited to) renal, breast, colon, pancreatic, lung, endometrial, ovarian, melanoma, sarcoma, and neuroectodermal tumors. Preclinical pharmacological studies have shown that MORAb-004 is a potentially useful anti-cancer agent. This clinical trial is being performed to determine the safety of MORAb-004 in subjects with solid tumors, as well as to establish serum pharmacokinetics of the antibody, and to assess tumor antigens that may serve as predictors of a response to MORAb-004. Study Part 2 was added to enroll subjects with specific histological diagnoses (colorectal cancer and soft tissue sarcoma) to further characterize the safety and tolerability of 5 dose levels of MORAb-004 previously tested during the dose escalation in Part 1.

Criteria

Inclusion Criteria:

Subjects ≥18 years of age.

Subjects with any malignant solid tumor without intracranial involvement or metastases diagnosed by standard pathology criteria that has failed standard chemotherapy.

Subject must have disease, as defined by RECIST or evaluable by clinical signs/symptoms (e.g., ascites, pleural effusion, or lesions of less than 2 cm) supported by biomarker, radiologic, or pathologic studies conducted within 4 weeks prior to study entry.

Karnofsky performance status ≥70%.

Female subjects of childbearing potential and all male subjects must consent to use a medically acceptable method of contraception throughout the study period and for 30 days after MORAb-004 administration. A barrier method of contraception must be included.

Presence of severe lung disease (In the absence of clinically apparent severe lung disease, no formal testing is necessary. In the presence of clinically severe lung disease, FEV1 must be >60% in order for the subject to be eligible.)

Breast-feeding, pregnant, or likely to become pregnant during the study.

Active hepatitis or human immunodeficiency virus (HIV) infection.

Subjects who have received a previous monoclonal antibody therapy and have evidence of an immune or allergic reaction, or previously documented human anti-human antibody (HAHA).

Subjects with large ascites or pleural effusion (≥500 cc) based on results of most recent CT scan).

Chronic systemic anticoagulation therapy with warfarin or heparin
